Paradoxical vocal cord movement (PVCM) refers to paradoxical adduction of the true vocal cords during inspiration resulting in variable upper airway obstruction. The condition often presents with shortness of breath, wheeze or stridor, mimicking bronchial asthma. Both organic and non-organic causes have been described. PVCM occurring only during sleep has rarely been reported in patients with CNS disease. We present a case of PVCM occurring only during sleep in a 14-year-old boy without any CNS disease, who was initially misdiagnosed as bronchial asthma.
矛盾性声带运动（PVCM）是指吸气时真性声带的矛盾性内收，导致不同程度的上气道梗阻。这种情况常表现为呼吸急促、喘息或喘鸣，类似支气管哮喘。已描述了器质性和非器质性病因。中枢神经系统疾病患者中仅在睡眠期间发生PVCM的情况鲜有报道。我们报告一例14岁无任何中枢神经系统疾病的男孩仅在睡眠期间发生PVCM的病例，该患儿最初被误诊为支气管哮喘。
